IMD mold, injection molding apparatus having such an IMD mold and method for producing a film-decorated plastic part

摘要

An IMD mold for producing a foil-decorated plastic part contains a half mold facing the foil and a half mold facing away from the foil. The two half molds can be placed on each other with corresponding mold dividing surfaces so as to form a cavity, which is substantially closed off from the outside, therebetween. At least the mold dividing surface of the half mold facing the foil is formed by an inner area surrounding the cavity and an outer area in turn surrounding the inner area.;The mold dividing surface in the outer area lies in an at least substantially flat or one-dimensionally curved mold dividing plane, and the mold dividing surface in the inner area is or can be set back with respect to the mold dividing plane.

主权项

1. An in-mold decoration (IMD) mold for producing a film-decorated plastic part, the IMD mold comprising:
a first half mold facing a film and having a mold parting surface; a second half mold facing away from the film and having a mold parting surface, said first and second half molds can be placed on each other along said mold parting surfaces and form between them a cavity being substantially closed off from an outside, said mold parting surface of said first half mold facing the film is formed by an inner region, surrounding said cavity, and an outer region, in turn surrounding said inner region, said outer region lying in a mold parting plane selected from the group consisting of an at least substantially flat mold parting plane and an one-dimensionally curved mold parting plane, said inner region being set back or can be set back from said mold parting plane; said mold parting surface of at least said first half mold facing the film forms, in said inner region, a collar which in cross section is set at a slope in relation to said mold parting plane; and said collar having a setting angle with respect to said mold parting plane of between 10° and 40°, and an amount of the setting angle varies around a circumference of said collar.
